we have a couple of C150s, running quite ok. Ever since enabling snmp traps both the boxes are bombing our management station with traps saying
Temperature has exceeded a recoverable failure threshold for probe (CPU_A)
Documetation says this trap is sent when CPU temp is above 90C. Also it suggests heatsink issue.
Before we set out on replacing the (new) boxes, we'd like to confirm it's real HW issue, but I'm unable to get any independent reading of the temperature probes. SNMP returns only "planar" temperature, which is cool:
SNMPv2-SMI::enterprises.15418.104.22.168.22.214.171.124 = INTEGER: 15
SNMPv2-SMI::enterprises.154126.96.36.199.188.8.131.52 = STRING: "Planar"
Upgrade from AsyncOS 5.5 to 6.1 made no difference.
In case of HW failure orange light should be flashing, too, and this is something the on-site personel couldn't confirm. OTOH, the LEDs seem to be hidden a bit on C150 ...
What would you suggest to do next?
